First up was a Ford Performance GT 670 HP Supercharger Kit. Developed with help from Roush Performance, the twin-rotor/four lobe blower bumps the 5.0L’s output to 627 peak horsepower and 549 lbs.-ft. peak torque—and does it on 93 octane pump gas. The kit comes with an intercooler, throttle body, cold air intake, fuel injectors and rails, and tuner.

Detroit Muscle also bolted on a Ford Performance Quad Exhaust Kit with rear and side exit outlets, finished with an Axle-Back System.

The chassis was upgraded with a Ford Performance Suspension Kit (springs, shocks and struts, anti-sway bars) and a Half-Shaft Upgrade Kit that features billet CV stub shafts and beefier axle shafts to handle the extra horsepower. The rear subframe used in the build is no longer available from Ford Performance, but a Mustang owner can stiffen up the stock subframe and reduce suspension flex with the Ford Performance Aluminum Bushings included in the Parts Combo.

Detroit Muscle finished the build with a Ford Performance Short-Throw Shifter Kit and a pair of Ford Performance Recaro seats with leather upholstery, race harness pass-throughs, and side airbags.
